HowTo Send Uploaded File with INPUT Type file to Sql Server Image Data Type

I have the following problem:

I have the following form client side:

<FORM.......>

<FORM action="./WZUpload.asp" method="Post" enctype="multipart/form-data"
WIDTH=100%>
<INPUT Type="file" name="UpFileName" STYLE="{Width:400px}"><BR>

I have the following ASP code server side ....

AllDataB = Request.BinaryRead()

AllData = ConvertToStringFromByte(AllDataB)

AllDataFile = pGetRequestItem(AllData....) ' THIS INSTRUCTION FIND FILE
BINARY DATA.....

I need to transform SAFE ARRAY AllDataB in a Vb string because it's
necessary for me to find Header info and because AllDataB doesn't contain
only FILE BINARY DATA but other informations.

Now I want to insert DIRECTLY File Binary Data (in the variable AllDataFile)
in a Sql Server Image field without writing AllDataFile to a local file
using the FileSysteObject.

If I write:

Rs("ImageField").AppendChunk AllDataFile

IT DOESN'T WORK: the data format is UNICODE. And If I open the file the
format is UNRECOGNIZED.

Is There a Mode to insert directly data from BinaryRead to Sql Server Image
data type ?

If I write data from binaryread to a local file with FILESYSTEMOBJECT and I
read it with ADODB.STREAM and I write ADODB.STREAM content to SQL SERVER
IMAGE DATA TYPE it works but it's VERY VERY slow with large files.

Thanks Rob

Hi Rob,

You may try following code to see if it will help:

Set objADO = CreateObject("ADODB.Stream")
objADO.Open
objADO.Type = 1
objADO.Write Request.BinaryRead(Request.TotalBytes)

Ok. But Request.BinaryRead doesn't contain only binary data of FILE but
other information : for example
CONTENT - TYPE
CONTENT - DISPOSITION....

etc etc.....
Now I must position at the begin of Binary Data.....I have tried with INSTRB
and MIDB but if I call INSTRB with Binary Data it goes in crash.

Hi Rob,

To remove the redundant data, you may refer to following article for third
party solution or pure script solution:

Addtionally, there is also a way with MSXML:
